I am using the NPC to output via USB to my MacBook Pro running Mavericks and using vinyl studio to store the files. I have the NPC set to output PCM at 24/96. I’ve tried recording to both AIFF and FLAC. Also, I have the I2S output on the NPC going to my DirectStream for listening while ripping. I make sure the settings in vinyl studio are set to PCM 24/96. When I start recording, everything looks ok initially (NPC is outputting at 24/96). However, after a song or two, I can see the bits on the display of the DirectStream drop from 24 to 16. Also when I play back the file that was recorded into the DirectStream, it starts as 24/96 for a half second the drops down to 16/96. This does not change whether I use flac or aiff.
This is would appear to be some kind of hardware issue in the NPC but I’m not sure. I have the latest firmware in both the NPC and the DirectStream.
Any help would be greatly appreciated.
